Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms exemplars methods may include placing an actuator in a tool containment interface of a handle; movable mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms and interface with the body catch and a force lever that forms an interface with the lever catch.

An example torque wrench is provided. The example torque wrench may include a drive head configured to engage with a tool for rotating a fastener. The drive head may have a drive axis about which the drive head rotates when rotating the fastener. The torque wrench may also include a deflection member coupled to the drive head and an outer body coupled to the deflection member at a first loading point and a second loading point. The torque wrench may also include a first strain gauge coupled to the deflection member between the drive head and the first loading point, and a second strain gauge coupled to the deflection member between the first loading point and the second loading point.

A tool includes an input portion, socket, arm, and sleeve. The input portion receives input torque about an axis. The socket is axially spaced apart from the input portion and configured to rotate a nut about the axis. The socket defines first and second apertures that extend through opposite ends of the socket into the socket cavity. A slot is open to the socket cavity and extends axially between the first and second apertures through a perimeter of the socket. The arm connects the input portion to the socket for common rotation. The arm does not extend completely about the axis. The sleeve includes a lower portion rotatable about the socket between a first position, in which the slot is open through a side of the tool, and a second position, in which the lower portion closes the slot to inhibit spreading of the socket.

A torque tool includes a body having a first end and a second end. A driving device includes a connecting portion and a driving portion. The connecting portion includes a pivotal end and an abutting end. The pivotal end is pivotably connected to the first end of the body. A torque device is mounted in the body, includes at least two elastic coefficients different from each other, and is disposed to be connected to the abutting end of the connecting portion. The torque device provides at least two torque ranges corresponding to the at least two elastic coefficients. An adjusting device is movably mounted to the second end of the body. The adjusting device is movable relative to the body to adjust a pressing force against the torque device to thereby set a torque value.

Presented herein are torque limiting drive tools for use with, for example, components of a medical device. A torque limiting drive tool in accordance with aspects presented herein comprises an elongate handle/body and a plurality of torque arms located at a distal end of the handle, where the plurality of torque arms define an opening configured to longitudinally (axially) receive a drive bit. The plurality of torque arms are each directly mechanically attached to the handle and are configured to exert a torque on the drive bit in direct response to rotation of the elongate body in each of a first direction of rotation and a second direction of rotation.

A torque socket tool is provided, including: a main body, a driving member, an engaging member, a torque adjustment assembly and a rotating member. The main body defines an axial direction and has a first restricting portion. The driving member is rotatably disposed on the main body about the axial direction. The engaging member is slidably disposed on the main body. The torque adjustment assembly includes a mandrel. The mandrel is disposed within the main body and rotatable about the axial direction. The rotating member is non-rotatably sleeved with the mandrel and has a second restricting portion.

A torque socket is provided. The torque socket includes a release mechanism that can be released when a torque thereof reaches a pre-determined value. The torque socket also includes a transmission module. The transmission module includes transmission members and a transmission shaft that are coupled with the release mechanism. The transmission members are cooperated with the release mechanism to determine the transmission shaft transfer torque or not to automatically release the torque,

Described are fittings, components, and associated tools for use in coupling pipe or tubing. The described fittings generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.

An torque warning structure is adapted for a rotary hand tool, and the rotary hand tool contains at least one rotatable pulling bar, one of the at least one rotatable pulling bar includes a fulcrum portion and at least one forcing portion. The torque warning structure contains at least one resilient element which is solely mounted or is jointly stacked on the at least one forcing portion, and each of the at least one resilient element has a pushing portion and a contacting portion between which a height difference is defined, the contacting portion contacts the at least one forcing portion, wherein the pushing portion drives the rotary hand tool to rotate, and when a pushing force of the pushing portion of said each resilient element is more than a deformation resistance of said each resilient element, said each resilient element deforms and makes warning sound.

Provided is an apparatus for applying a specific amount of torque, comprising a body, a torque wheel, rotationally affixed to the body, comprising a plurality of teeth around an outer edge and a central spring mechanism affixed to and enclosed within the body, the central spring mechanism, comprising a spring stop and a torque spring, the torque spring comprising a torque spring end wherein the torque spring end engages the plurality of teeth and wherein, in a first rotational direction, the engagement of the torque spring end in the plurality of teeth prevents the torque wheel from rotating with respect to the body below a specified amount of torque and wherein, above the specified amount of torque in a second rotational direction, the torque spring flexes enabling the torque spring end to disengage from the plurality of teeth and enabling the torque wheel to rotate with respect to the body.
